Title: Railway track resonance and vibration insulating mat - has interlocking top lengthways engaging ribs and parallel bottom support ribs
Inventor: GLANG SIEGFRIED
IPC: E01B2/00
Filed: 1977-11-17
Abstract: The insulating matting is made up from strips (3) of rubbery material set close together, with parallel support ribs (5), on the underside, for vibration and noise insulation on railway tracks, esp. on bridges or in underground or tunnel-type structures.

Title: Compression ignition engine fuel injection system - has unloader valve downstream of pump opened by delivery pressure
Inventor: RINGWALD PETER
IPC: F02M69/04
Filed: 1978-10-06
Abstract: The system injects fuel into the intake of a mixture-compressing engine, the intake containing an adjustable throttle and an air measuring device one behind the other. The device moves according to the air flow rate in opposition to a return service, and actuates a control slide in fuel measuring and distribution valve. Fuel is delivered by a pump into the supply pipe, and from there passes into a control pressure pipe with one or more control valves. A pressure chamber connected to this pipe generates the force on the control slide. In the supply pipe down-stream of the pump is an unloader valve (56), whose movable plug (57) is thrust open by the pressure of the fuel from the pump and by a compression spring (58), and shut by the fuel pressure downstream of the valve. The spring is so designed that the plug opens under slight pressure of the fuel downstream above atmospheric, partic.

Title: Vibration operated compacting press - has vibrator between upper and lower mould, transmitting mechanical energy directly onto blank
Inventor: FASSBENDER NORBERT ING GRAD
IPC: B30B11/02
Filed: 1978-10-14
Abstract: The press operating by vibration achieves homogeneous compacting of the workpiece material by applying dynamic pressure produced by a vibrator onto the workpiece. The press uses a mass which is brought into co-vibration by the vibrator, while the vibrator frequency is equal to the inherent frequency of the total mass, so that resonance is produced. The press has pneumatic cylinders, which reduce the oscillation via the pressed workpiece in dependence of vibrator housing amplitude. During this process the inherent frequency of the oscillation is subcritical.

Title: Single sided polishing of domed or curved glass panes - via pneumatic polishing membrane driven by eccentric, esp. for mfg. mirrors
Inventor: FLOETENMEYER MAX
IPC: B24B19/26
Filed: 1978-11-02
Abstract: A disc is fitted with vertical pillars employed to support a curved or domed pane underneath a polishing head. The head consists of a hollow cylinder with an open base covered by a membrane which is elastic and contains a polishing agent; and pressure, esp. via compressed air, is exerted on the membrane so it forms a curved or spherical surface matching the surface of the pane. The hollow cylinder is driven by an eccentric so it moves in an orbit during polishing. Membrane is pref. covered on its underside with a diamond-shaped grid made of felt, the distances between the strands of felt being smaller than the length of the stroke of the eccentric drive. Compressed air is pref. fed via an accurate pressure into the cylinder to distend the membrane. The surface of the polishing head always matches the contour of the panes.

Title: Cable clamp suitable for sailing boats - has cable inserted between two sloping toothed rollers with sliding clamping action
Inventor: VOSS GUNTER
IPC: B63B21/08
Filed: 1979-04-12
Abstract: The cable clamping device has a V-shaped base plate (10) with two sloping lugs (13) at the wide end and two smaller sloping lugs (12) at the narrow end, supporting two spindles (15) between them. Each spindle carries a clamping roller (18, 19) which has a rear sleeved part (23) and a larger diameter headed part (20, 21). Each head has a series of circular gripping teeth (22) around it. When a cable (26) is inserted between the clamping rollers, it can be rotated to assist the teeth to embed in the cable, and tension towards the narrow end of the device results in a clamping action, due to the angle of the spindles.
